micro-led显示系统及应用

micro-led技术在近十几年来随着gan蓝光led芯片技术逐渐成熟而发展起来,并在最近开始引起人们广泛的关注。micro-led作为新一代显示技术,其高亮度、高可靠性及反应时间快、低耗电等特点,在可穿戴、柔性显示、透明显示、车载显示等领域具有极广阔的应用前景。这项新技术已陆续吸引了众多跨国公司积极投入。例如,2014 年苹果斥资 7亿美金收购了微led 屏幕技术公司 luxvue;2016年,facebook收购了英国mled; 2017年,google 注资瑞典公司glo,发展micro-led全彩技术;2017年末,三星展出基于micro-led的巨型电视拼接墙(准确的讲是小间距led电视),把micro-led 显示技术的商业化发展推进到了一个新的高度。

本方向主要开发高分辨率micro-led显示器以及其在vr/ar、智能手表、google glass、可穿戴电子产品等领域的应用。
